To all whom it may concern.-

Be it known that I, CHARLES 7. KING, of

Newton, in the county of Middlesex and State of Massachusetts, haveinvented certain new and useful Improvements in Hand Tacking- .Machines,of which the following is a full,

clear, and exact description.

This invention relates to a machine for antomatically driving tacks ornails one after another, and intended to be used more especially inconnection with a machine for lasttical section; Fig. 3 aplan view.Fig.4 represents a detail plan viewbelow line 44 Fig. 2;

Figs. 8 and 9 are perspective views of one of theparts intwo different positions. Fig. 10 is a detail horizontal sectionjust above the horizontal section'of' Fig. 5. Fig. 11 is a detailpfrontor end view. .Fig. 12 is a detail plan view. Fig. 13 is a detail sideview of one ofthe parts;

In the drawings A represents the body of. the machine tacker, B a handlefor grasping and holding it by the hand,O a receptacle for l the tacksconsisting of a vertical-cup, which is adapted to screw on to the upperend of the body as at a, open at its bottom, and having 1 two horizontalpartitionsD, E, therein which freely fit the internal sides of the cupand'are connected together by a central post F, which extends down belowthe lower partition E, and has secured to its lower end the lower end ofa curved tube G which at its upper end is secured to: the lowerpartition at one side or edge of the partition and at such place has anopening H communicating with the chamber of the tube, the tube having alongitudinal open slot K, in its side extending throughout its length ina spiral direction and where the tube is secured to the partition, thepartition is cut away outside of the diameter of the tube in a smallV-shaped opening L, over such -spiral slot.

' The upper partition D has an elongated opening M at one side as shownin Fig. 3, and it has four vertical pins or wires 19, which passthrough'it, extending-above and below the partition, the upper partitionalso having a central vertical handle N by which the partitions can bereinoved t'rom the receptacle whendesired; the receptacle has a cover Pwhich fits over its upperend'to'close it, and it is held in place by afour armed spring plate Q secured at its center to the inner side of thecover, each arm being bent down as at d and of the receptacle. A pin eprojects radially and horizontally from the inner side of therecepforming a spring, to bear against the inner side tacle and theupper partition has an open slot f 7a in its edge which when thepartitions, and more particularly thetube or spout, is'in the properplace engages with the pin and prehaving an opening or slot h in itsedge which enables it to freely pass by or over the pin e. Thehole Mthrough the upper partition is on the opposite side of the receptacle tothe opening H in the lower partition communicating with the spirallyslotted spout or tube.

In the body is an inclined raceway R which is shown in longitudinalcentral section in Fig. 2, and in plan in Fig. 5, this raceway down tothe point m being in the body of the machine, and it is continued in'ablock S which is inserted in a recess n in the machine body. Thisraceway consists of a longitudinal vertical groove 1" and in the bodyeach side extends upward from the groove being inclined as shown incross section in Fig. 7.

Opposite the lower end of the raceway in the block S is a small cylinderor block T which is arranged to make a partial turn, or

revolution or swing back and forth on'apivot u in a chamber or socket oin the block but block S partially over the socket, by a plate 3 securedin a depression a in the under side of the block, which plate and theportion to of the block serve to hold the pivot u for the cylinder.-Across one side of the cylinder T is an opening I) in which is avertical pin (1 against which pin is arranged to bear a flat spring 6secured in a recess in the side of the block by a screw.

g is a vertical slot in the side of the cylinder which when it is in itsnormal position is opposite to or coincident with the end of the racewaygroove 7'. In this cylinder just below its top is a horizontaltransverse open slot it one end of which opens into the farther side ofthe vertical slot g and the other end terminates in an opening m in theupper end of. the cylinder, below which last opening m is another deeperopen horizontal slot n. Against its shoulder r is arranged to bear theround end 15' of a pin V arranged to move back and forth in a horizontalsocket u in the head U of the body, and in an opening 1) in the block Sas shown in section in Fig. 5 more' particularly.

In the block S diagonally back of the opening '2) in which the cylindermoves and communicating therewith, and just back of the lower end of theraceway groove 1', is a vertical opening W which extends down to andcommunicates with an inclined passage A as shown in dotted lines in Fig.2. Extending inward horizontally into the cylinder socket 'v is a thinpointed piece, arm or stripper a of the block S which horizontally is inposition to project freely into the horizontal opening 71 in thecylinder as shown in Fig. 10.

Adapted to slide up and down between two arms B of the head U is thetack driver, plunger or bar C consisting of a portion 1) substantiallyoblong in cross section, its lower portion being in the form of a rod orspindle D which extends down through a socket d in the head of largerdiameter than the rod and open to its outside at c bya space smallerthan the socket but large enough for the rod D to be moved out throughit, the lower end of the driver rod D extending down into asocket E inthe foot portion Fof the head to freely slide up and down therein. Thedriver has two shoulders f which abutagai'nst the under sides of thearms Bot' the head as a stop to the upward movement, and the lower end72 of the square portion abuts against the shoulder 'm of the head as astop to the downward movement, respectively of the driver Around thedriver spindle or rod D is aspiral spring G which is disposed in thesocket cl bearing against the shoulder a and against the under side orend h -of the driver which acts by its tension to keep the driver at itshighest position and to return it thereto if moved down and free tomove. The side of the driver nearest the cylinder has avertical-longitudinal groove or slot H which is opposite to and in linewith thesocket u in-which the pin V is arranged to slide back and forth.

The lower surface of this slot extends outward to the side in a downwardinclined direction, as at r shown in section in Fig. 2, making aninclined bearing surface for the pin V for operation thereof as will behereinafter described.

Below the socket E the foot has an open space i from side to side intowhich project pieces J K one at each side of plates re spectivelypivoted to the head at a meeting in the center, the adjacent side ofeach piece havinga vertical tapering groove, making as a whole atapering socket L above socket o in the lower end, these pieces beingarranged respectively to swing to and from each other within the openspace 25 A spring M secured to the head by screws to hears by its forkedfree ends against a shoulder a on the piece K to keep it closed, and onthe opposite side of the head is another spring N secured by a screw 12which bears against the inner side of the piece J" to keep it in itsclosed position. The inclined passage A opens into and communicates withthe side of the passage E for the driver rod just above the conical ortapering socket-L of the two swinging pieces.

A plate P is secured on the top of the block S which covers over theraceway therein, having a narrow longitudinal groove h which is over theraceway groove in the block, which plate groove is too narrow to allowof the escape of the tacks,'but open enough for the operator to see theheads as they pass along the raceway, the plate being high enough orgrooved longitudinally on its under side to allow free passage oftheheads of the tacks, between it and the raceway.

The portion of the raceway in the body of the machine is covered by aplate Q which has a longitudinal groove 111, over the raceway groove,which is not wide enough to allow the tacks to escape butsufficientlywide to allow the tacks to be seen as they pass along theraceway. The upper end of this plate has two lugs v on its under sidewhich fit in between the sides 20 of the body and a horizontal plate Swhich projects into the chamber T of the body below the opening in thebottom of the receptacle, in which plate is an elongated opening U. Thelower end of this plate is in two parts or arms V V each of which has anunderlug W,they both fitting in between the sides w of the body and arearranged to press against the side by the spring of the arms, holdingthe plate in place. On the side of each arm V to this plate is a smallprojection g by which the two arms can be pressed toward each other whendesirous of removing the platefrom the body.

The operation of the tacker is substantially as follows: Tacksare placedin the receptacle on top of the upper partition, and the cover placedthereon, t he tackerbei n g-held i n the left hand, which is then shakenuntil the tacks have passed down into and through the spimny slottedtube, the heads of the tacks pass ing dow-n'the inside of the tube withthe points The head of the driver is then struck a quick hard blowwhichforcesthe driver down until it is stopped by theabutmentof: itsend'orshoul-= der, against the shoulder of the head; its spiral springthen acting to moveit :back to its nor- .mal position. With the driverin its upper position,- the pin. V rests-against'the part A bf thedriver,which holds the cylinder in position against its spring 6': forthe notch or opening g'tobe inline with the lowerendf of the race- Waygroove so that in such position the tack will freely pass into theopening or'notchin the. cylinder from the raceway:as described. As. thedriverjis forced down the spring e. is allowed to exercise its pressureto turn the cylinder on its axis, in the .direction of the arrow Fig 9by the pin V passing up the incline r into the groove H in the side ofthe driver and; as the. cylindertso turns the tack in the notch oropen-ingis carried with it, and is forced against. the point or arm'ctextending :into the horizontal-slot h." which forces the tack to move,out of itscylindernotch,

and-the cylinder having moved so that the notchg' will be in line withthe passage 'W the tack is finally moved off-the cylinder anddroppedointo. this passage down which 'it passes, and th roughv theinclined passage A into the passage E above'the tapering socket L' inthe two pivotedholders, and then into such tapering socket, the driverinthe mean time-having risen fromthe action of its spring, outofthe way ofthe travel of the tack. The tack being now imposition to beidriven bythe driver, the foot of the machine isthen placed on the articlewhere-the tack. is to be used andthe driver fOI'C/QdLdOWIPfiS before,which drives the, tack into thearticle in positiontherefor, and lets thecylinder springact uponit to move the second tack forward which in themean time has passed into the openingin the cylinder, to be forcedoutward by the point, into the passage down which it drops, and passesto and stops against the driver rod which has passed down by the passagein driving the tack, but as: soon as the driver rod rises and returns toits normal position, the tack drops down into the tapering socketbetween the two pivoted pieces and is there held as before to be drivenby a blow upon the driver. Thus after the first tack has been allowed topass down into position to be driven, by the operation ofthe parts asdescribed, at

each blow on the driver, a tack is driven and another is moved intoplace to bedriven and.

so on as long as there are tacks in the machine. Just over the handlethe body is cut away each side of the raceway making openings into achamber f i-n the handle, to allow the tacks that may-not be in theraceway to drop into it out of. the Way rather than on the floor, toberemoved at pleasure by unscrewing the screw g in the handle.

The carrying cylinder or block need not be round, although itis'preferable to have. it so,

the cylindrical form being best adapted for its work" and itsparts inrelation to the other part of the machine;

There is an opening in the plate P over the passage W in the block Sinwhich rests a knob E on the under sideof a spring arm Fise'cured by ascrew G to theplate P. which can be sprung up and swung to one sideleaving the opening and passage W exposed to viewso that it can becleared of tacks if it should accidentally be clogged. The driver isinserted in place by placing the spring over its rod portion,t-hencompressingit closely against the shoulder k and inserting thespindleportion through the open spacee into itssocket d andplacing itssquare portion in its seat when the lower end of;the.spiral springwillpass down into its socket, and when in place, a plate HHS secured on theoutside by screws J which keeps all parts in place and yet allowsfreemovement of the driver up and down.

.In Fig. 3 the cover is removed from the receptacle showing the upperpartition in plan View.

.The. pins 1) extending through the: upper partitionoserve to keepthetacks separate so that they will pass more freely down through thereceptacle. 1 o

. As the passage W is atone side of the-central longitudinal line of theraceway, which is in-line with the vertical axial line; of the driverrod, the inclinedpassage-A' inclines toward such central longitudinalline, as well astoward the driver rod passage E to make propercommunication with: the passage. The opening m in the upper endrof thecylinder or blockT allows the cylinder tobe insertedyin its chamber fromthe under side of the-block S byfreely passing over the end of the armor stripper a Having'thus described my invention, what Iclaim'is V 1.
